Would be good to collate this information in the OP too, which will help me in future when editing the "Vehicle History" for each vehicle on the site's fleet lists, i.e:

3801:
January 1999 - Transferred to Stanley
February 2003 - Transferred to Percy Main from Stanley
March 2005 - Vehicle repainted into whatever livery.

4901:
May 2000 - Transferred to Percy Main
July 2004 - Transferred to Gateshead from Percy Main
August 2006 - Vehicle repainted green for "Lime" services 8/78.

Personally don't mind if it goes right up to present day as it saves me a job at the end of the day!
